dc.description.abstractWe study the nature of the new signal reported by LHCb in the 𝐽/πœ“β’π‘ spectrum. Based on the 𝑆-matrix principles, we perform a minimum-bias analysis of the underlying reaction amplitude, focusing on the analytic properties that can be related to the microscopic origin of the 𝑃𝑐⁒(4312)+ peak. By exploring several amplitude parametrizations, we find evidence for the attractive effect of the Ξ£+𝑐⁒¯𝐷0 channel, which is not strong enough, however, to form a bound state.en
